I too will line up to praise B&H.
But, OP, it seems you're in Costa Rica. Be careful about shipping. For all of B&H's many, many fine qualities, their shipping to addresses not in the continental US can be a serious problem.
I live in Hawai'i, and I've ended up buying items (such as cameras and lenses) from Amazon rather than B&H because of B&H's breathtaking shipping costs to what is, after all, part of the US.
For example, I bought my D810 from Amazon rather than from B&H, even though I wanted to give B&H my business. Why?
If I go to buy a D810 at B&H today, it's listed as having "free expedited shipping," but when I put in my Hawai'i ZIP code, suddenly the least expensive shipping (UPS ground, which means ground to the west coast and then air across the Pacific) is $29, UPS 2 day is $43, USPS Priority Mail is a whopping $67 and FedEx 2 day is $99.
This is nuts -- and so for Costa Rica you're probably going to be looking at something that's even nuttier.
It's a pity because in absolutely every other way, B&H is first-rate.
